COMBINED SASH-BALANCE, ILOCK, AND ANTIRATTLER.

SPECIFICATION formingpart of Letters Patent No. 646,042, dated March 27, 1900. Application led September 23, 1899. Serial 110,731,434. (No model.)

To all whom it may concern:

Be itknown that we, DANIEL R. SHEEN and JAMES A. PHILBRICK, citizens of the United States,residing at Peoria,in the county of Peoria and State of Illinois, have invented certain new and useful Improvements in a Oombined Sash-Balance, Lock, and Antirattler for Windows; and we do hereby declare that the followingis a full, clear, and exact description of the invention, which will enable others skilled in the art to which it appertains to make and use the same.

This invention pertains to a combined balance, lock, and antirattler for windows.

One object thereof is to furnish windows with a simple arrangement forbalancing the sashes thereof.

The further object is to provide this arrangement as a substitute for the cords and weights usually employed.

Furthermore, the object is to furnish means for preventing the rattling of the s ashes of windows without causing them to bind or sacriiice the free vertical movement thereof.

Lastly, the object is to combine with a device of this character means for locking the sashes of Windows, and thus do away with the usual well-known class of window-locks which cause so much annoyance.

In the appended drawings, Figure 1 is a cross-section of a window-casing, showing the two sashes and the invention in position for work. Fig. 2 is an elevation of a windowframe and its sashes, showing the knob for operating the device. Fig. 3 shows a portion of the sashes of a window, one of which is partly broken away to show a rack-bar therein. Fig. A is an enlarged view of part of Fig. 1, showing a rack-bar in cross-section, together with a gear-wheel adapted to mesh therewith. Fig. 5 is an elevation of the same. Fig. 6 shows a ratchet and pawl for use on the inside of the window-casing. Fig. 7 is plan view of Fig. 1, enlarged, showing an operating-spring around the shaft. Fig. 8 is a perspective view of the sashes at their junctures, showing the protruding ends of the vertical bars thereof. Fig. 9 shows part of the sash of a window having a modified form of balancing mechanism therein. Fig. 10 is still another form of the same arrangement. y

In the several iigures, A is the window-cas- .spring L sustains it.

ing, B the sill, and C D the upper and lower sash, respectively. A horizontal shaft E in the casing at the juncture of thesashes and at right angles thereto is journaled at one end in a plate F, secured to the casing, and the inner end of said shaft is carried in a similar plate G on the casing within the room. While we prefer to support the shaft in this way, other means may be used, as is obvious. The said shaft carries two gears H and I, the former being loose thereon and the other fixed, as by a key J, Fig. 1. To the shaft also two revoluble wheels K K, are secured .having beveled edges, as in Figs. l, 4, 5, and '7.

These may be fastened to the shaft or to the gear-wheel mentioned, as desired. A spring L surrounds the shaft and has one end secured to the plate F in suitable manner and the other to the wheel I. A similar spring M surrounds the other extremity of the shaft and is likewise fixed to the wheel H at one end and the plate G at the other. are wound in contrary directions, asshown, the purpose of which will be presently shown. The edges of the sashes are grooved or plowed out at N, Fig. 3, and a rack-bar O is placed therein and made adjustable by means of the slotted extremities P and suitable bindingscrews Q. The rack-bars extend beyond the ends of the sashes where the latter come together at the middle, as in Fig. 8, and since the shaft E is located also at that point, Fig. 3, both of the bars are engaged at once by the gears. Such bars are grooved longitudinally at R beyond the cogs and engage the said plates, as shown. This combined mechanism we use to prevent the rattling of the sashes, to which all windows are subject.

The gears and the said plates are constantly in' engagement with the bars N. When the upper sash is in its usual closed position, the

sash, the spring is tightened, and the lower it is carried the more tension is applied to such spring. However, the spring is of such length that the increased tension does not necessarily raise the sash from any position in which it may have been placed, but merely sustains it in that position. In moving this sash the shaft is turned with the gear-wheel, as is evident when we remember -that the said gear and shaft are xed together, and

The springs When lowering the IOO since the gear H is loose on the shaft neither it nor the lower sash will be affected. When the lower sash is closed or in its down position, the spring M is under as much strain as would be sufficient to sustain the weight of the sash when raised or opened to any position, but need not be enough to raise the sash from its closed position. Both springs are of sufficient length to store sufficient power for the purposes named without opening the window in the manner stated and are wound in opposite directions, because the sashes operate in opposite directions. The means employed for locking the sashes consists of a ratchet S, secured to the shaft outside the plate G, with which a pawl T is adapted to engage, the latter being pivoted to the said plate. The upper sash may by this arrangement be locked at any elevation desired, as is evident. The lower sash may also be locked at any height by means of a pin U, parallel with E, and operated inside the room by a knob V. The opposite end of the pin is supported by means of an eyebolt or equivalent means W, driven into the casing, and is adapted to enter one of a series of apertures in the face of the gear H. Thus it will be seen that either sash may be operated separately or independent of each other, and by the pawl and ratchet and the pin U the upper and lower sashes, respectively, can be locked independently or at the same time. XVe provide a handpiece E for the shaft E for use in raising or lowering the upper sash or to revolve the shaft, if desired, in either direction in order to better lock the ratchet by means of the pawl. XVe have provided for the sagging of the sashes by making the rack-bars adjustable, whereby the latter may be at all times in a perfectly-upright position. Fig. 3 shows the adjustable idea and will be easily understood. XVe employ one of the combined balances described at each side of the window, as indicated in Fig. 2, so that the sashes will work evenly and smoothly. The device on the left side of the window, Fig. 2, does not necessarily have the knob V or the handpiece E', though we may use them. Neither are the pawl and the ratchet necessary, but simply the shaft E and its loose and fixed gear, together with the springs, which latter must be set in a reverse position to the corresponding ones at the right side of the window, for the reason that the gears operate in a reverse direction, as is evident.

In Fig. 9 is shown a modified form of the device, and consists in providing a hollow gear-wheel, in which is seated a spiral spring, one end being secured to the inner periphery of the gear and the other to the stationary stud onwhich the gear revolves. The rackbar is secured to the casing, and as the window is raised and lowered the spring is p ut under strain to accomplish the desired end. Fig. 10 has the same general arrangement, except that the parts are reversed as to location-i. e., the rack-bar is fastened to the sash and the spring-drum to the casing; but the same results are obtained as with the other form. Suitable locking mechanism may also be provided for these forms. We may use the antirattler, lock, and balance either in its combined form or use the several ideas separately.

XVe are aware of an arrangement somewhat the same as ours, but its parts are complicated and costly, and such a device cannot accomplish the results that ours do. By placing a device as we construct it at each side of the window in line with the juncture of the upper and lower sashes and extending the rackbars R, as in Fig. 8, to meet them we preclude the necessity of using more than two of such arrangements for the window, whereas in the arrangement referred to four are necessary.

Having thus described our invention, we claim- 1.
